LAN/WAN, firewalls, VPN, SD-WAN, and infrastructure — delivered under Weltenmarkts
Reliable networks are the foundation for every modern business — but design, security, and migrations need specialist skills. Weltenmarkts scopes network projects and coordinates delivery with our vetted Senior Network Engineer, so you get one point of contact and enterprise-grade execution on routing, switching, firewalls, VPN, SD-WAN, F5 load balancing, and infrastructure support.
Typical deliverables
- Network design and documentation
- Firewall, VPN, and SD-WAN deployment
- Routing, switching, and VLAN configuration
- F5 load balancing and high-availability setups
- Migration, testing, and operational handover
Problems we solve
Unstable or undocumented networks
Ad-hoc changes, missing diagrams, and unclear ownership lead to outages and slow troubleshooting when something breaks.
Security gaps at the perimeter
Weak firewall policies, outdated VPN setups, and missing HA put business continuity and compliance at risk.
Branch and remote connectivity pain
Sites struggle with reliable WAN, DMVPN/SD-WAN design, or consistent access control across locations.
Our approach
Design-first delivery
Documented topology, VLANs, routing, and security policies before changes hit production — with validation and rollback planning.
Multi-vendor expertise
Cisco, Huawei, Fortinet, Palo Alto, and F5 — migrations, HA pairs, VPN (IPSec/SSL), and load balancing where your stack requires it.
Weltenmarkts coordination
You work with Weltenmarkts for scoping, communication, and accountability; our network specialist executes under agreed standards and handover.
